lApplication.filed J une 3, 1904. Serial No. 210,999.

To @ZZ whom 'it may concern: l

Be it known that I, MILTON A. FEsLEE, a citizen of the United States, residing at Visalia, in the county of Tulare and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to improvements in oil-burners especially adapted for burning crude oil.

The primary object of the invention is to vprovide a simple and reliable means for regumovement of the regulating device.

A still further object is to improve upon` the jet shown and described in Letters Patent No. 714,468, granted to me November 25, 1902.

Other objects and advantages resulting from this construction will become apparent in the course of the following description, and the points of novelty will be set forth ,in the claims.

vIn the drawings illustrating the invention, Figure 1 is a side elevation of the vaporizingjet, showing a portion o f the steam and oil connections, which may be the same as those shown in my patent above referred to. Fig. 2 is a central vertical section of the jet and a slidable cap for controlling the passage of the oil from the jet and regulating the same. Fig. 8 is an end view of this cap, showing more clearly the form of opening therein. Fig. 4: is a detail perspective view of the vdevice for accomplishing the regulating movements of the movable jet parts. Fig. 5 is an enlarged perspective view of the end of the nozzle. Fig. 6 isa detail perspective view ofthe cap valve, showing its relation to the device for increasingor diminishing the opening in the cap; and Fig. 7-is a perspective view of a de-l tached portion of the nozzle end.

Referring to the drawings, the numeral l indicates the nozzle, preferably formed with a tapered end, as shown, as is usual in devices of this character, but which, as will appear later on, is made to perform a function in connection with the cap-valve that will be described. This jet is formed with an upwardlyprojecting branch 2, externally threaded, as indicated by the numeral 8, for a portion of its length for the reception of a suitable union or joint, with which the jet is connected with the steam-generator. (Not shown herein, but clearly shown in the patent referred to.) The numeral 4: designates the second branch, internally threaded for the reception of the oilsupply pipe 5, leading from vany suitable source, the oil in which pipe is maintained below the nozzle by gravity or other force at the proper point. The nozzle is provided with a narrow oil passage or duct 6, comlnunicating with the central bore of the branch 4 and opening at the end of the nozzle, at-the under side thereof, into the space 7, between the end of said nozzle and the cap-valve 8, all of which will be presently more fully described in connection with the mechanism for operating the regulating device.

The numeral9 designates the branch through which Works a needle 9', which is the same as and adjustably secured in oblique slot 14 in the rocker arm or lever 15, pivoted to the jetcasting at 16 and extending a short distance below the pivot,asindicated by 17. The lower` end of this arm is provided with a slot 18, in which is also pivotally and adj ustably secured the vrear end of the rod 19, which rod has its forward end pivoted to the side of the capvalve 8, as shown in Fig. 1.' The upper end of the arm 15 is bifu'rcated or forked, as indicated at 20, the tines of the'fork straddling IOO the forward end of a shaft or stem 21. The end of the shaft is provided with two collars 22 to form abutments for the upper end of the arm 15, so as to rock said arm on its pivot when the shaft or stem is moved for the purpose of adjusting the parts. This stem or shaft passes through an internally-screwthreaded boss 23, rigidly secured to the jetcasting, and is itself threaded for a portion of its length, as indicated by the numeral 24, and is provided atits rear end with a hand-wheel 25.

To prevent the cap-valve 8 from turning, and thereby changing the position ofthe elongated opening or slit 28 therein, I provide it with a lug or projection 27, through which is eut a vrecess 28, which is occupied by a rod 29, rig- `it will ride through said recess.

idly secured to the jet-casting at a point where This rod 29 is inclined upwardly from the casting, as

:function than to merely guide the cap valve and prevent it from turning, as will now be described.

shown in Figs. 1 and 2, and serves a further The numeral 30 indicates a hinged lip which operates in a recess 3l in the slidable capvalve 8 and is provided on its upper side with a standard 32, having an eye 32', through which works the rod 29, which rod being stationary and inclined will cause the lip 30 to move vertically up or down to enlarge or diminish the size of the opening in the cap, which is advantageous to more efectually atomize the oil under varying steam-pressures or varying quantities and consistencies of oil. To cooperate with this feature of the device, I provide the end of the nozzle with a movable end section 83, provided along its top edge with a spline 34, adapted to be engaged by the under side of the movable lip 30 when the cap is moved rearwardly. This movement of the nozzle end will diminish the size of the opening in the nozzle, and consequently control the steam-pressure, making the same greater or less at the nozzle, as the needs of the case may require. Thus with a low steampressure. with the cap moved rearwardly to 'the desired point, the nozzle end would be contracted, increasing the pressure at this lpoint. While accomplishing this result by moving or slidingthe cap rearwardly, the oil- `supply is reduced to a certain extent by reason of the closer proximity of the cap to the rnozzle end, and at the same time the movable lip will descend and provide an opening where- .with the oil is caused to be more thoroughly vaporized. Of course it will be understood that the reverse movement of the cap, which Vresults in disengaging the lip 30 from the 'spline 34, will permit the nozzled end to open .wider and cause the lip to be lifted, thus increasing the outlet from the nozzle, as well as 'from the cap-valve.

Y Although the operation of the device has been fairly suggested in the foregoing description, I will nevertheless for the purpose of more clearly understanding the same now describe it. Assuming the desired relation between the nozzle and the cap valve has been predetermined and the rods 13 and 19 correspondingly adjusted in the slots in the arm 15 and the burner working well under prevailing conditions and it is desired to regulate the openings in the steam and oil passage to accommodate the jet to other conditions, the hand-wheel is rotated or, rather, partially turned in one direction or the other, depending upon the oil and steam supplies desired or required, and by reason of the thread on said stem engaging with those in the lug 23 the stem will be moved backward or forward, as the case may be, and will by reason of its connection with the upper end of the arm 15 rock said arm, which in turn and through themedium of rods 18 and 19 move the cap and needle to or from each other, thus increasing or diminishing the volume of mixed steam and oil that is ejected from the jet into the lireboX or combustion-chamber. A rearward movement of the cap will cause the lip 30 to move down to diminish the size of the opening in the cap-valve and cause the needle to diminish the steam-supply, thus increasing the steam-pressure at the end of the nozzle to a degree where it will be in proper proportion to the amount of oil to be atomized. The reverse movement of these parts will be desirable with an increased steam pressure, which movement will cause the lip 30 to be lifted and increase the size of the opening in the cap-valve, the steam-pressure with this movement being free to lift the movable end of the nozzle, this movable portion of the nozzle being now free to move upward by reason of the disengagement of the under side of the lip 3() from the spline 34.

While I have shown and described a construction wherein the movements of the ncedle and the cap by reason of the connections between them are somewhat dependent upon each other, I do not desire to be understood as limiting myself in this particular, for it is obvious that the needle adjustment may be accomplished independent of the cap valve, as is usual in devices of this character, or may be dispensed with, in which event the escapement of steam from the nozzle would be controlled or regulated by reason of the engagement or disengagement of the cap with or from the movable nozzle end. The degree of movement of the needle and cap valve is governed or regulated by the position the rod ends occupy in the slots 14 and 17, which is determined by the character or consistency of the oil used and the steam-supply desired or required to most effectually atomize the oil IOO IIO

both rods would result in dilferent movements of the .needle and cap. f It will be understood thatJ the movable en i of the nozzle is operated upon. by the cap when to be heated.

While I prefer that the oil should be supplied through the oil duct or passage 6. and the steam throughthe central passage in the nozzle, it is obvious that this order may be reversed and the oil' fed through the passage 10' and controlled by the needle and the steam supplied through the passage or duct 6 andv controlled by the cap-valve 8.

I claimtherethrough, of a suitable oil and steam supply, an adjustable cap-valve fitting over said nozzle, a needle movable in said nozzle for the purpose set forth, and connections between said cap-valve and needle whereby they are moved together in opposite directions to regulate the oil and steam supply, substantially as described.
